I have mixed and matched parts on the pee wees and never ran into a problem with drive plates or any other parts. Do you have a pic of the part?

I've found 2 different sizes. One on the tapered case and one on the straight case.

I just got an email from Matt, he said the 90's and up version has a larger shaft end/drive plate.

Yes, and after further research I think the larger diameter crankshaft splined ends/driveplates ones may have been earlier than just the 90's. I pulled a few Skycopter cases (late 70's) and they too had the larger crank/driveplate combo.

This goes for both round and the hex driveplates.

If anyone has any more concrete info it would be appreciated.

Yeah,

I would like to know more. I recently aquired a really early pee wee. Really pronounced taper case, no step/wrench relief cylinder backplate has no screen no markings and no thimble drome on the red tank. The drive plate is chewed up from pliers and I was going to get a replacement for it but, now I am not sure what will fit or what to be looking for. I really thought they were all the same. This thing looks brand new apart from the driveplate.

Sounds like the 2 I have. I don't think red "new" drive plates are available.

No, I don't think so. Not readily available but, they do pop up on Ebay more often than not. NOS that is.

I have been toying with the idea of home anodizing. Might save a lot of money in the long run. Especially since most replacement parts are Estes non-anodized stuff.

Hmmm,

Looks like same length except one has more bearing surface.

What's the diameter?

would the bearing surface cause the engine to overheat?

I wouldn't think so. Unless the shaft was a really poor fit and even then it probably wouldn't even run
